Sometimes homeowners want to install the biggest AC system available because they believe it will provide superior home comfort. However, the truth is an oversized system will not do a better job of cooling the house or provide any extra comfort over a properly sized unit.

Air conditioner size is calculated in BTU (British Thermal Units) and tons, and measures how much heat the system can remove from the home in one hour. For example, a one-ton air conditioner can remove 12,000 BTUs of heat per hour. Cooling a house faster means taking away less of the uncomfortable humidity.

While a bigger air conditioner will not cool the house faster, it could cause some serious problems including:

• Short-Cycling – When the AC is not properly matched to the home’s size, it could turn on and off repeatedly, which wastes energy and causes excessive wear and tear on the system.
• Decreased Home Comfort – When a system short-cycles, it doesn’t have time to distribute cooled area around the home, leading to warm spots.
• Increased Humidity – An oversized system typically doesn’t remove humidity as well as a properly sized unit because it’s not able to run long enough to pull moisture from the air.

When upgrading to a new air conditioner, it’s important that you partner with a reputable installation company that can accurately calculate your cooling load, provide you with AC options that fit your needs and budget and can answer any questions you have.
